---------------------------------------------------------------------------
Key: HADOOP-2816
URL: https://issues.apache.org/jira/browse/HADOOP-2816
Project: Hadoop Core
Issue Type: Improvement
Affects Versions: 0.15.3
Reporter: Robert Chansler
In one example:
Cluster Summary
Capacity : 1.15 PB
DFS Remaining : 192 TB
DFS Used : 717 TB
DFS Used% : 62 %
Why is Capacity not equal Used plus Remaining?
(The answer is that there is an estimated reserve for local files.)
The presentation should be easily understood by the user.
